If strictly followed, no danger should occur. This machine must only be run by qualified adult persons who are fully aware of possible dangers. Directives ZH 1/406 and BGR 500, as well as relevant national safety rules to be followed. The machine is not suitable for unattended operation and must be operated according to specification. Protective clothing to be worn. Suitable ear protection to be worn. The water jet emerging from the spray pistol has a dangerous cutting effect. Therefore the water jet must never be directed onto persons, animals or electrical installations. It must never be used for cleaning of clothes, footwear and the like. Be aware of torque and recoil. Ensure stable foothold. The max. allowed pressure which is stated on the type plate must not be exceeded. The safety/control valve opens, if the max. operating pressure is exceeded by more than 20 bar and returns the water into the suction side of the high pressure pump. The safety/control valve is workshop-set and sealed. Adjustment must not be changed. Machines driven by combustion engines must not be run indoors unless proper ventilation and exhaust gas evacuation are guaranteed. Exhaust gas is harmful, excessive concentration of carbon monoxide is lethal. Unsuitable respectively defective high pressure hoses often cause severe accidents during operation. Therefore high pressure hoses to be carefully inspected before start-up and replaced by original OERTZEN equipment in case of damage. Use of other than original OERTZEN equipment (hand nut marked with OERTZEN), results in expiry of the EC Declaration of Conformity, as well as product liability and warranty. Used or damaged high pressure hoses must never be repaired and reused but to be replaced by original OERTZEN equipment. Spray pistols with delayed closing mechanism must not be used because of risk of injuries. Lever in open position must never be blocked or fixed in any way. Use of spray wands of a length below 750 mm is prohibited. The machine must not be run in areas jeopardized by fire or explosions. During operation at filling stations Technical Rules for flammable Liquids (TfbF) to be observed. Consumables to be handled thoroughly according to technical rules and safety and environmental regulations to be observed. 4

5 Before opening the machine in case of malfunction or emergency, switch off by means of the emergency switch. Electric power is harmful. Any symptoms for faulty electrical components to be taken seriously and cause to be eliminated immediately. For repair work machine to be disconnected from power supply Make sure that the machine cannot move. If the unit is equipped with a parking brake, it must be set during working. During loading hoisting device to be fastened properly at jack rings. Ensure balanced load. The exhaust evacuation area is hot! Do not touch! Repair work in the high pressure section of the machine (pump, hoses, piping) only to be carried out by qualified personnel. After work the machine to be locked and secured against unauthorized/accidental operation by means of the safety lever.

6 3. Configuration/Illustration The machines of this series consist of a high pressure inline plunger pump, driven by a low-emission air-cooled 4-stroke Diesel engine. In case of poor oil pressure an alarm lamp is illuminated. Depending on the model, the motor is equipped with rope start or electric start, respectively both alternatives. The feed water is directed via a pre-filter to the high pressure pump which in connection with the required spray nozzle boosts it to the stated/adjusted working pressure. Downstream of the high pressure pump a locked and sealed safety/control valve is installed which opens as soon as the operating pressure is exceeded by more than 20 bar and returns the water which cannot be taken by the nozzle into the suction line of the pump. It also allows to continuously adjust working pressure and water flow as required. By opening the adjusting knob at the double lance the working pressure can be adjusted as required. In parallel, when detergent dosing valve is open, detergent will be injected into the water jet at low pressure. The machine is equipped with a circulation shut-off system and additionally with a thermo valve in order to protect the pump against overheating. After closing the spray pistol the safety/control valve opens, and returns the circulating water back into the suction line. If the the temperature of the circulating water exceeds 60 C, the thermo valve opens, releases small amounts of hot water and allows cold water to enter. Re-starting and immediate generation of required/adjusted working pressure is achieved by opening the spray pistol again, allowing to continue the cleaning task without delay. The range of applications can be extended by a variety of accessories available. Contact your local distributor. 6

High pressure hoses, hose pipes, whether damaged. Air supply, fresh air grill must not be covered. Filling of consumables. Correct oil level of high pressure pump (sight glass/dip stick). Correct oil level of Diesel engine (dip stick). Only oil qualities approved by OERTZEN to be used. High pressure pump: special pump oil OERTZEN OSP, reduction gear: special pump oil OERTZEN OSP, Diesel engine: OERTZEN special motor oil OSM. Pump/pump connections whether leaking. Machine only to be run with absolutely clean water. Before connecting the water supply hose, rinse it thoroughly. Depending on feed water quality, regularly check water filter in short intervals, replace if needed. Machine only to be run horizontally (+/- 5 ). In order to extend the lifetime of the Diesel engine, engine to be warmed up for a few minutes during starting procedure and to run out during shut-down for cooling purposes. In order to guarantee proper function and trouble-free operation, the following checks to be carried out during working: Observe function of indicator lights/monitors. Observe pressure variations Observe leaks at high pressure pump, hose pipes, connections. Observe excessive exhaust formation/smoke development. Observe abnormal noise. In case of malfunctions immediately stop machine, eliminate cause according to chapter Trouble Shooting, call qualified service. 8

9 Connections Water inlet (6) and high pressure water outlet (11) are protected with sealing caps which must be removed before start-up. It is recommended to protect water in- and outlet with those caps during extended shut-down periods. Water Supply Connect water inlet (6) of the machine to water source with a clean hose of " diameter. Before connecting water supply hose, rinse it thoroughly. In case of connection to the potable water distribution, observe DIN 1988 (for momentary connections use a backflow preventer with non-return function and ventilation). Flow pressure minimum: 2 bar maximum: 8 bar The machine can take water from vessels, open waters with a max. suction height of 1 m. Never use polluted water because this would damage pump, safety/control valve and spray pistol. Insufficient water supply will cause heavy damage on high pressure pump (cavitation). High Pressure Connection Connect high pressure hose to high pressure outlet (11) by means of the hand nut without using tools. Diesel Supply Diesel tank (37) to be filled with Diesel (min. 45 cetane). Properly lock tank. Diesel and Diesel vapour are highly flammable and explosive. Fire and explosions may cause severe injuries or death. Diesel never to be handled near hot engines. Fuel to be handled with care. Observe engine manufacturer s instructions and applicable safety regulations. 9

10 Operation Fully open water source, respectively dip in strainer. Turn hand wheel of safety/control valve (3) counter-clockwise, in order to ease engine start. When starting engine observe engine manufacturers operating instructions! Start Procedure Rope Start: Turn fuel cock (37 a) into position "O" (open). Put adjusting lever (49) into position "START". Take handle of starter rope (52) and pull it out up to resistance. Let the handle return into initial position. Push decompression lever. When pulling the starter rope the lever automatically returns into its initial position. Strongly pull starter rope in order to start motor. Start Procedure Electric Start (option): Turn fuel cock (37 a) into position "O" (open). Put adjusting lever (49) into position "START". Turn starter key into position "START", release key, as soon as engine starts. Start attempts should not last longer than max. 15 seconds, in order not to damage the starter. Unlock and release spray pistol. Warm-up motor at low pressure. Put adjusting lever (49) into position "RUN". Increase working pressure as required by turning the hand wheel of the safety/control valve clockwise up to max. allowed pressure. Open spray pistol and carry out cleaning task. Be aware of significant recoil. Ensure stable foothold. Pressure Regulation By opening and closing the adjusting knob at the double lance working pressure can continuously be adjusted.
